Matematik 1c
The first maths course on the Natural Science and Technology programmes.
Matematik 1c lays the ground for all the maths that follows: numbers, algebra, functions, geometry and statistics. Since the Gy25 reform, which started in autumn 2025, the course is called Matematik, nivå 1c.
Overview
Most students take Matematik 1c in their first year of upper secondary school, and for many it is the first time maths moves from calculating to reasoning. You are asked to explain how you know, to set up an equation from a situation described in words, and to choose a method yourself instead of following a worked example. That shift, more than any single topic, is what makes the course feel hard at first.
The course is also where habits form. Algebra that is shaky in 1c tends to cause trouble in every later course, while students who learn to write their solutions clearly carry that into the national test and beyond. The test at the end has parts with and without a calculator, so practise both. If the course is going well, aim to understand why the methods work; if it isn't, start with algebra and percentages, which almost every other topic builds on.
What you learn
-
Numbers and algebra
Powers, prefixes, expressions and equations.
-
Percentages and change
Percentages, change factors and exponential growth.
-
Functions
Linear and exponential functions, their graphs and what they describe.
-
Geometry
Geometric concepts, Pythagoras' theorem and trigonometry in right-angled triangles.
-
Probability and statistics
Reading data and diagrams, and working out probabilities.
How it's scored
Your teacher sets the grade (A–F) from everything you have shown during the course. The national test is weighed in specially, but it doesn't decide the grade on its own.
How to prepare
- Practise without a calculator: the national test has parts where you can't use one.
- Show how you think. Much of the credit is for method and reasoning, not only the answer.
- Work through old national tests that have been released, under the real time limits.
- Fix gaps in algebra early: every later course builds on it.
